Contact WPG or an authorized dealer for more information. -
Page 12: Indirect Loading
1..Although lifter use may be possible at higher elevation, lifting capacity is reduced whenever the lifter is unable to attain vacuum in the green range on the vacuum gauge. Contact WPG for more information. 2..Special provisions may allow the lifter to operate outside the specified temperature range. Contact WPG for more information. MRTA(4)6LP6FAC: #35259... -

Page 17: T O Lift And Move The Load
OPERATION IFT AND OVE THE Lift bar must be vertical to lift load. About the Tilt Linkage The tilt linkage minimizes operator effort and Unbalanced loads may tilt automatically holds a balanced load in either unexpectedly during lifter operation. the upright or the flat position. However, an Make sure load is positioned unbalanced load may tilt unexpectedly, correctly on lifter. -
Page 18: Controlling The Lifter And Load
OPERATION Controlling the Lifter and Load When the lifter is ready, use the hoisting equipment to raise the lifter and load as needed. Use a control handle (circled in fig. 1A) to keep the lifter and load in the required position. Once there is enough clearance, you may move the load as required. -
Page 19: T O Rotate The Load
OPERATION OTATE THE Make sure load is positioned correctly on lifter (as previously directed). 1) Make sure the load has enough clearance to rotate without contacting anyone or anything. Use a control handle to Unbalanced loads may rotate unexpectedly when keep the load under rotation latch is disengaged. -
Page 20: T O Tilt The Load
OPERATION ILT THE Keep hands and fingers away from tilt linkage. 1) Make sure the load has enough clearance to tilt without contacting anyone or anything. 2) Use the control handles to keep the load under control at all times. 3) Lift upward or press downward on the tilt control handle (arrows in figs. -
Page 21: T O Release The Pads From The Load
OPERATION ELEASE THE ADS FROM THE Make sure load is at rest and fully supported before releasing vacuum pads. Push the vacuum release button ( — fig. 1A), to break the vacuum seal. Do not move lifter until pads release completely, because such movement could result in load damage or personal injury. -
Page 22: Storing The Lifter
OPERATION Storing the Lifter Disconnect the electrical connectors (figs. 1A-B). Use the covers supplied to keep the vacuum pads clean (fig. 2A). CE/UKCA — To prevent the lifter from tipping over on relatively horizontal surfaces, place the vacuum pads facedown on a clean, smooth, flat surface. Be careful to protect the vacuum pads while tilting it to the horizontal position. -
Page 23: Inspections And Tests
2..The Periodic Inspection is also required whenever the lifter has been out of service for 1 year or more. Keep a written record of all Periodic Inspections. If necessary, return the lifter to WPG or an authorized dealer for repair (see “REGISTRATION AND LIMITED... -

7) Prepare a written report of the test and keep it on file. 1..An equivalent simulation may also be used. Contact WPG for more information. 2..A “qualified person” has successfully demonstrated the ability to solve problems relating to the subject matter and work, either by possessing a recognized degree in an applicable field or a certificate of professional standing, or by possessing extensive knowledge, training and experience. -
Page 27: Maintenance
MAINTENANCE Note: Refer to SERVICE MANUAL #35275 when applicable. ACUUM AINTENANCE Pad-to-Load Friction Coefficient The friction coefficient represents the lifter's ability to resist load slippage. The Maximum Load Capacity is based on a friction coefficient of 1, as determined by testing of clean, new, standard rubber vacuum pads on clean, dry, regular glass. -
Page 28: Pad Cleaning
4) Allow each pad to dry completely before using the lifter. 1..A brush with bristles that do not harm rubber can help remove contaminates clinging to sealing edges. If these cleaning methods are not successful, contact WPG or an authorized dealer for assistance. MRTA(4)6LP6FAC: #35259... -
